Across
- 2. complex, represents ventricular depolarization
- 6. the more the myocardial muscle is stretched the greater the contraction
- 8. tropy, increases or decreases heart rate.
- 10. 40-60bpm
- 12. ventricular repolarization
- 13. 60-100bpm normal pacemaker
- 15. 1st and relaxation phase allows for ventricular filling
Down
- 1. ability to propagate the electrical impulse
- 3. determined by preload, contractility, and afterload
- 4. 2nd and contraction phase ventricular emptying
- 5. when the heart can not be stimulated to depolarize
- 7. heart sound of the atrioventricular valves closing
- 9. positive deflection representing atrial depolarization
- 11. outermost protective sac of the heart
- 14. tropy, strength of cardiac muscle contraction
- 15. tropy, rate of nervous impulse contraction
